BABY_PRODUCT Bambino Mio Reusable Nappy Set, Bug's Life, One Size, 1 count

Why are the shown prints in the picture not the prints that are actually delivered? I only received 1 of the prints from the picture. .

What material are these diapers made of?

How many times are we supposed to wash these ones to prep them? Ive read all over the add & the packaging but dont see any amount! Please help lol

I’m new to the cloth diaper world. do i need both the mioliners and the mioboost? do i always need a mioboost for these diapers? thank you
